Bit of a weird one, hope this is the appropriate venue:
I've just purchased some Ethernet-over-power adapters that were returned to and repackaged by a brick and mortar retailer. I'm trying to be more vigilant with security recently and was wondering: should I be concerned in at all that these devices could have been loaded with malware or something nasty?
I know this may be paranoia but I am sharing this internet connection with others and am mindful of something that will be connected directly to the router. Any advice would be greatly appreciated. Thanks
